Given numbers are 981,403,325,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,403,325,128 is 1265097600.
Find LCM of 981,403,325,128 with Prime Factorization
13 | 981, 403, 325, 128 |
981, 31, 25, 128 |
Multiply the prime numbers at the bottom and the left side.
13 x 981 x 31 x 25 x 128 = 1265097600
Therefore, the lowest common multiple of 981,403,325,128 is 1265097600.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
981 x 403 x 325 x 128 = 16446268800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
981 : 1, 3, 9, 109, 327, 981
403 : 1, 13, 31, 403
325 : 1, 5, 13, 25, 65, 325
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,403,325,128, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
403:13x 31
325:5x 5x 13
128:2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 16446268800/(1x13)
LCM = 16446268800/13
LCM = 1265097600
Thus, we can understand that the LCM of 981,403,325,128 is 1265097600.
